Due to an out-of-control obesity epidemic that cuts across demographic lines, the average American's risk of developing diabetes is "very high," a troubling report concluded. The report, conducted by investigators for the Centers for Disease Control and Prevention, was based on data from a National Health and Nutrition Examination Survey. Investigators surveyed more than 3,000 adults nationwide, finding that overall diabetes risk was startlingly high on average and tended to increase as a person's body mass index (BMI) increased. The risk that an obese man will be diagnosed with diabetes is 57%, compared with only about 20% for normal-weight men. Diabetes risk also tends to increase as blood pressure increases, researchers found.
